Comment 4 for bug 1665555

Hi Pooja,

If a volume is already attached when attaching a volume, we don't error out and just return success. If a volume is already deleted when deleting a volume, we don't error out and just return success. Similarly here when a volume is already added to a group, we don't error out and just return success.

I don't see the value of checking updated volumes by timestamp to find what volumes are added to a group. Users want to know whether volumes are in a group or not. They can get that by viewing the details of a group. They can also find out whether a volume belongs to a group or not by viewing the volume details.
